Looks like they are in your bathtub…And a lot of chicks. They are so cute. But have your dust mask ready..lol.

Since you have some past experience, I expect you remember how fast they grow. Mine really surprised me and at only one week old, I was out shopping for a larger brooder. I don't think the space will accommodate them more than another week? The light needs to be rigged to be able to raise it about once a week and not risk a turn over or fall on the chicks.

Please check out the Learning center articles on raising baby chicks, and the amount of space they need.

If you haven't already done so, make sure you have your coop plans and start building. you will need to move them out at 5-6 weeks old.
